This linear ball bearing enables linear motion along a shaft through recirculating ball tracks arranged in an open, machined design. Bore diameter is 16.0 mm and outside diameter is 26.0 mm, with a net mass of 37.36 g. It is sealed on all sides, protecting the raceways from contamination while retaining lubricant inside the unit. A relubrication facility allows grease to be replenished without dismantling the bearing from its application, which supports maintenance over extended operating periods. The open design permits mounting on shafts with support ribs, and a corrosion-resistant version of this construction is available, extending its use in environments where moisture or aggressive media would otherwise affect the raceways.
